Basically, Farrah accused Catelynn and Tyler of making "poor choices," and said she was "very sad to hear" about their second pregnancy. Obviously, Catelynn and Tyler defended themselves, but Farrah has since taken to Twitter to throw even more shade!

"Over #TeenMomDrama," she tweeted. "Glad I moved on #DoorSlammed wish those #StillTeens all the best when your [sic] not a Teen #QuitPlayin."

So many hashtags, so little time. Farrah clearly has a lot of resentment towards Teen Mom (not to mention her former co-stars), and she also seems to think that they're still teenagers.

Well, Catelynn and Tyler are actually the same age as Farrah, and Cate was quick respond on Twitter to imply who exactly is the immature one in this situation. "She's just mad because WE are classy and don't sell our bodies," Cate responded. "lmao she's the one who needs to grow up."

Looks like we have a Teen Mom feud on our hands! And while judging Farrah for her sex tape is kind of a cheap shot, we totally understand why Catelynn is so offended by her critical comments.
